My default is set to 15 right now because k00b gives me too many sats. I've done 1,000 sat tips before though because I was just really happy to see the post. I don't have a high bar to tip though. If a post had me learning something new about the world, 15 sats. If someone is arguing with me in the comments, were the arguments well thought out? Tip. Is the argument dumb in the first place? Don't tip. This is to encourage people who stimulate my brain even if I don't agree with them.

So as you see, the default doesn't always mean I tip that amount.
